Synthetic Or Natural Fiber

Opalite

Synthetic Opalised Glass

Aura Quartz

Silicon Dioxide (SiO2) with Titanium/Metal vapor coating

Red gemstone ring, likely synthetic ruby or red glass; exact stone cannot be confirmed from the image

Ruby (corundum, Al₂O₃) if natural; the setting appears to be silver-tone metal

Red cabochon gemstone ring, likely synthetic ruby or red glass

Possibly corundum (Al₂O₃, chromium-colored); identity cannot be confirmed from the image

Cubic Zirconia

Zirconium Dioxide (ZrO2)

Goldstone

N/A (Synthetic Glass with Copper Inclusions)

Diamond (in jewelry)

Cubic Carbon (C)

Goldstone (Brown)

Aventurine glass

Goldstone

Aventurine Glass (Man-made)

Opalite

Synthetic Glass, SiO2 base with metallic inclusions

Decorative opal-like turtle mosaic

Likely imitation or assembled opal material; exact stones cannot be confirmed visually

Gold-colored gemstone ring, likely citrine or glass imitation

Indeterminate from image; possible quartz (SiO₂) or yellow glass set in gold-colored metal

Ruby

Corundum (Al2O3)

Loose faceted colorless gemstones, likely quartz or glass-like mineral chips

Most consistent with quartz (SiO₂), though the photograph cannot exclude synthetic cubic zirconia or glass

Diamond (or Diamond Simulant)

C (Carbon) or synthetic equivalent

Blue opalite (often sold as synthetic opal)

Opalite glass; amorphous hydrated silica if natural opal (SiO₂·nH₂O)

Ruby

Corundum (Al2O3)

Colorless faceted gemstone (likely cubic zirconia)

Cubic zirconia, zirconium dioxide (ZrO₂); possibly synthetic quartz or glass imitation

Moissanite

Silicon Carbide (SiC)

Diamond (or Cubic Zirconia)

Crystallized Carbon (C) for Diamond; Zirconium Dioxide (ZrO2) for CZ

Diamond (or Cubic Zirconia simulant)

C (Carbon) or ZrO2 (Zirconium Dioxide)

Emerald

Beryl (Be3Al2(SiO3)6) with Chromium/Vanadium impurities

Cubic Zirconia

Zirconium dioxide (ZrO2)

Silicon Carbide (Carborundum)

Silicon Carbide (SiC)

Opalite

Synthetic Opalized Glass / Man-made Glass

Diamond or Cubic Zirconia

Carbon (diamond) or Zirconium dioxide (cubic zirconia)

Orgonite Pyramid (containing Amethyst and mixed minerals)

Silicon Dioxide (SiO2) in synthetic resin

Blue Quartz / Glass Gemstone Pendant

SiO2 (Silicon Dioxide) or Synthetic Glass

Sapphire

Corundum (Al2O3)

Opalite

Synthetic Glass (Simulated Opal)

Clear faceted gemstone, likely synthetic cubic zirconia

Cubic zirconia (zirconium dioxide, ZrO₂); visual identification is not definitive and diamond or synthetic moissanite are alternatives

Faceted purple-blue beads, likely synthetic glass or treated gemstone

Indeterminate; possible synthetic corundum, synthetic spinel, or dyed quartz (SiO₂)

Opalite

Synthetic Opalized Glass (SiO2 + additives)

Turquoise-colored ring stone (possibly turquoise or imitation)

Turquoise, CuAl₆(PO₄)₄(OH)₈·4H₂O; identity cannot be confirmed from the image

Opalite

Opalescent Glass (SiO2 + coloring agents)

Ruby (mounted cabochon)

Corundum, Al₂O₃; red color typically from chromium

Opalite (Synthetic Opalized Glass)

Synthetic Silicon Dioxide (SiO2) glass

Cubic Zirconia

Zirconium Dioxide (ZrO2)

Faceted colorless gemstone, likely quartz (rock crystal)

Quartz, SiO₂

Red faceted gemstone, possibly ruby

Corundum (Al₂O₃), if ruby; image alone cannot confirm identity or natural origin
